The key to charming your dragon in manhwa is through bravery and loyalty. Stand by its side in difficult times and prove your worth. Additionally, using special powers or gifts might help win its heart.
Based on the information you provided, I can recommend the following novels to you:
1. Emperor Leng's Poison Doctor: She was as elegant as an orchid, and her dual cultivation of medicine and poison was unfathomable. Everyone thought that she was rotten wood that could not be carved and that she was useless. The Green Mountain had been silent for ten years. When the wind and clouds were surging, she waved her hand and became famous. However, after she had won the hearts of many men, she suddenly disappeared…
2. [Supreme Martial God: In the Ancient Martial Continent, the strong are respected.] A woman who was as calm and elegant as a chrysanthemum rose from a useless woman who could not gather true qi to a Supreme Martial God who could destroy the world with a snap of her fingers.
I hope you like this fairy's recommendation. Muah ~😗
